N. EL, ASSIGNGPU TO THE INTERNATIGNAL CQRK CQIVIPANY, OF IB'EOOI ILYI'I, NEW YORK, A CORPORATION OF NEN YGRK.

GURK-DOGKING MACHINE.

To all whom it may concern Be it known that I, Annxaivnnn BocniNrrr, a subject of the King; of Hungary, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful improvements in Cork-Docking Machines, of which the following is a specification.

The present invention relates to cork docking machines, or more particularly to an apparatus for reducing the cork to its proper size and finishing; the ends thereof.

fine of the objects of the invention is to provide a. simple and efficient device of this type, whereby, in a continuous operation, the corks are reduced to their proper sizes and both ends of the same are finished simull'aneously.

Another object of the invention to pro duce a novel and improved work-holder" which rotates continuously, and is adapted to receive the corks and to present them in their proper positions to the cutting and finishing means.

A further object of the invention is to provide a simple feeding device which delivers the corks to the work-holder, and which is actuated by and moves in unison with said work-holder.

With these and other objects in view, which will more fully appear as the nature of the invention is better unc'ierstood, the same consists in the combination, arrange: ment and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and minor deails of construction within the scope of the a upended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of a machine constructed in accordance with the present invention; Fist. 2 is a front elevation of the same; Fig. is a plan view of the workholder; *l is a section taken on line li of Fig. 3; Fig. 5 is a sectional view of the cutting means; Fig. 6 is a sectional view of the finishing" or grinding means; Fig. '6 front elevation of the feeding means;

Serial No. 717,753.

Fig. 8 is a plan view of the feeding means; Fig. 9 is a front elevation of a detail of the feeding means; Fig. 10 is a plan view of the detail shown in- Fig. 9; Fig. 11 is a bottom plan view of a detail of the work-holder; Fig. 12 a plan view of a belt tightening means used in connection with the cutting means of the machine; and Fig. 13 a section taken on line 1313 of Fig. 12.

In the drawings, the numeralQO indicates the frame of the apparatus, comprising a casing-like structure, having apertured side walls which support a horizontal frame plate In this frame plate is rotatably mount ed a vertical shaft 22, carrying upon its upper end the work-holder 23 hereinafter to be described. The lower end of the shaft 22 is supported in a step-bearing 2i, througl the box of which extends a set screw 25, adapted to lower or raise the shaft 22 and the parts carried thereby. To the shaft 22 is attached above the frame plate 21 a spider like block 26, to which is secured by means of screws 2, or otherwise, ahorizontal disk 28 a substantial distance above the frame plate 21. The disk, forming; the base plate of the work-holder, is provided with a con tral circular opening 29, and with a plurality of arc-shaped slots 30 near its peripheral portion. In each of the slots 80 is ar ranged a stationary jaw 3 and a movable jaw 3?, the latter being attached to or, preferably, made integral with an arm 33, which is pivoted at 34. in any suitable manner to the underside of the disk 28. The pivot of each arm 33 comprises, preferably, a bolt 35, having an extension 86 projectingtoward the frame plate 21, and around this cXtension is coiled a spring 37, one end of which is secured to the extension 36, while its other end 1s fastened to the arm 38, and tends thus to hold the movable aw 32 against the stationary jaw 31. The stationary jaws are provided with notches 38 and the movable jaws with notches 39, which register, when the movable jaws contact with the stationary jaws, forming thereby apertures in which the corks are adapted to be seated. The ends of the arms 33 project toward the axis of the shaft 22, and are adapted to be acted upon by a cam 40, which is arranged in the opening 29 in the disk 28. The cam is provided with an upwardly extending sleeve 41, drawn over the reduced portion &9 of

the shaft 22. The upper end of the sleeve is screw-threaded, as shown at 43, these threads being in mesh with those of nuts eat and 45, the nut f le being attached to an arm e6, which is held between stops at, l? upon the frame plate 21. The purpose of the arm 46 and the stops e7, cooperating therewith, is to hold the cam d0 in the proper position relative to the arms 33 upon the workholder. The upper end of the shaft L2 is also screw-threaded, as shown at as, and these screw threads mesh with a nut 49. If the nuts 49, i5 and 4:4: are loosened, the cam can be shifted around the axis of the shaft 42 to vary and predetermine the points at which the movable jaws will open and close.

The means for feeding the corks to the workholder comprises a bracket 50, the base 51 of which is attached to the frame plate 21. In this bracket is shiftably mounted a vertical feeding tube having a flaring mouth 53. Into this feeding tube, which is adapted to be lowered into the slots 30 as they pass under the same, are placed by hand or fed through a chute the corks to be docked and finished. The corks are fed onto an arc-shaped support 54, which is adj ustably held on the bracket 50 by means of a set screw 55, engaging the support and a vertical slot in the bracket. The support Fri is arranged below the disk 28, and its distance from the frame plate 21 can be varied. The purpose of this arrangement will be hereinafter explained. The means for lowering the feeding tube 52 into the slots 30 in the disk 28 and for withdrawing the same from said slots comprises a lever 57, whicl is fulcrumed at 57 to the bracket 50, said lever having a notch 57". in which is seated a pin 52, carried by the feeding tube The free end of the lever 57 carries a roller 58, which is arranged in the path of a plurality of cams 51 upon a ring 62, the latter being fastened to the upper face of the disk 28. In order to permit of an adjustment of the cams relative to the roller 58, the ring 62 is provided with slots 63 in engagement with set screws 64-. which fasten the said ring to the disk 28. To the bracket 50 is furthermore pivoted at 65 a swinging lever 66, having a cam-shaped recess 67 in its rear face, in which is seated a pin 68, the latter being adjustably mounted upon the lever 57. To the lower end of the swinging lever 66 is adjustably fastened. by means of a set screw 69 a finger 70, which is adapted to project through a slot 71 into the feeding tube spring 72, attached to the bracket 50 and the swinging lever 66, tends to withdraw the finger '70 from the tube 52. The cams 61 are arranged in such a manner relative to the slots in the disks 28 that, whenever a slot arrives into registering position relative to the feeding tube 52 (in which position the movable j aw 32 in said slot does not contact with the stationary jaw therein),

the roller 58 is lowered into arecess in the cam ring 62 by its own weight and that of the feeding tube In this position the finger T0 is withdrawn by the spring 72 from the feeding tube, whereby a cork will. be deposited into the arcshaped slot to rest on the support 54. In the further rotation of the disk 28, the roller 58 is forced upward by one of the cams G1, withdrawing thereby the tube 52 from the arc-shaped slot 30. At the same time the pin 68 forces the swinging lever 66, against the action of the spring 72, toward the tube 52, or in other words it causes the finger TO to project into the tube 52 and to prevent thus the next cork in said tube from being fed onto the support When the next slot in the series arrives into registering position reh tive to the tube 52, the said tube is a gain lowered and the operation now described is repeated. After the cork is deposited into one of the slots 30, the movable jaw is gradually disengaged from the cam 40, whereby the said jaw will move under the action of its spring 37 toward the stationary jaw, which will, in cooperation with the movable jaw, grip the cork and present it to the cutting means.

The cutting means comprises a disk cutter which is attached to a shaft 74, the upper end of which is rotatably mounted in a block 7 5, which is carried by a bracket 76, provided upon its lower end with a stepbearing 77, in which is journaled the lower end of the shaft T l. A set screw 78 serves to raise or lower the disk cutter 73 to permit the cork to be cut at the proper place, or in other words to reduce the cork to a predetermined size. The disk cutter rotates above the disk 28 of the work-holder, so that by setting the support 5% or the dis; cutter 73, the size of the cork can be easily predetermined. As the disk cutter must be sharpened from time to time, and its diameter thus naturally reduced, means must be provided for shifting the shaft 7% and the cutter carried thereby toward the work holder shaft 22. F or this purpose the bracket 76 is shiftably aranged upon the frame 20; the means for shifting the same comprising a screw threaded spindle 79 meshing with threads in lugs 80, 80 upon the frame of the machine, said spindle being rotatably carried by the bracket 76 and having at its outer end a hand wheel 81.

After the cutting operation has been performe the corks are presented by the workholder to the grinding means. The grinding means comprises two parallel horizontal grinding disks 82 and 83, for instance emery disks. The disk 82 is attached to a vertical shaft 84, which is journaled in the frame plate 21, its lower end being sup ported in a step-bearing 85, which is provided with a set screw 86 for a well known purpose. The disk 82 has an upwardly extending screw threaded sleeve 87, over which fits a screw threaded sleeve 88, which carries the disk 88. A locking nut meshes with the threads upon the upper end of the shaft 84-. It will be observed that the dis tance between the disks 82 and 83 may be varied, at will. The disks 82 and 83 are arranged on opposite sides of the workholder. The peripheral. portions of the disks 82 and are slightly tapered, as shown at 01. and 9-2, respectively, whereby the corks will be ground down gradually to their proper sizes.

The main driving shaft 93 of the machine is journaled in bearings 94, 9%. Upon this shaft mounted a loose pulley 95 and a fixed pulley 96, by the intermediary of which rotation is imparted to the shaft. A belt 97 running over pulleys 98 and 99 upon the driving shaft 93 and the shaft 84c, respectively, transmits rotation to the shaft S i and thus to the grinding disks 82 and 83. Rotation is imparted to the shaft 74 of the cutter by a belt 100, running over pulleys 101 and 1052 upon the driving shaft and the shaft 74;, respectively. A pulley 103 is keyed to the shaft T l, and over this pulley runs a belt 104 in engagement with a pulley 105 upon the shaft 22 of the work-holder. As, however, the distance between the shafts T l and 22 is to be varied as above described, obviously a belt tightener or stretcher must be provided. This belt tightener comprises two plates 100, 106, which are fulcrumed at 107, 107 to the frame plate 21. Each of the plates 100 carries two rollers 1.08, 108, which engage opposite sides of the belt 104. Links 109, 109 are pivoted at 110 to the block 45 and at 111, 111 to the roller carrying plates 100. A shifting of the block 75 will result in a swinging of the roller carrying plates 106 around their pivots 107, causinp; thereby a tightening of the belt 104-.

The operation of the machine is as follows: According to the length of the corks to be finished, some of the parts of the machine must be set. Here particularly the support 54 is shifted, the cutter 73 must be shifted by means of the set screw 78 to a proper distance from the upper face of the support 54; the distance between the grind ing disks 82 and 83 must be set to correspond to the length of the corks, and furthermore the shaft 84L shifted to bring the grinding disks into proper relation to the work-holder disk 28. The corks are placed into the feeding tube When now rotation is imparted to the main driving shaft of the apparatus, the cam 40 will cause the swinging jaws 32 to swing around their pivots away from their coacting stationary jaws a suitable distance before a slot 30 arrives into registering position with the feeding tube. V'Vhen a slot arrives at this point, the jaws are fully separated. The fecdin tube is lowered in a manner above described into the slot, and the finger 70 withdrawn from the tube, whereby a cork will be de msitcd onto the support 5%. In the further rotation of the worlenolder, the feeding tube is withdrawn from the slot and the cork moved. by the stationary in the slot along the arc-shaped support 54L until gripped by the two cooperating jaws in said slot. In this manner it conveycd to the rotary cutter 73, which reduces the cork to its proper length by slicing off a cork disk from its upper end. T he cork is then brought by the closed jaws between emery 'lisks which will simultaneously grind or linish both ends of the same. In the further rotation of the work-holder, the jaws i-ieparatc, releasing the cork when it arrives above an aperture 112 in the frame plate :3- through which it drops into a chute 11 -3. to be delivered thereby into a receptzu rlc located under said chute. The jaws re main open, and. when they arrive again opposite the feeding tube, the operation now (lescril'icd is repeated.

it is obvious that. while herein the operation of one pair of jaws has been described, the others act in the same manner, so that a continuous operation is obtained. The grinding disks and the cutter rotate at a higher rate of speed. than the workholder.

it is to be observed that instead. of the workholder herein ttlescribed, any other endless conveyor construction can be used within the scope of he appended claims.
